NUS’ sustainability agenda was first broached in 1997, when the Campus Green Committee (CGC) was formed. Comprising of only volunteers from both the academics and administrators like professors, lecturers and the staff of NUS, CGC’s vision back then was to create a cleaner and greener environment and one of the first projects implemented was the ‘Clear Your Own Tray’ campaign which was aimed to eliminate the problem of birds feeding on leftovers after meals. The campaign not only successfully served its purpose but it also brought a greater awareness of how individuals can do their part in incorporating sustainability into their daily lives. Following the success, staff and students have become much more pro-active and committed in transforming NUS into a sustainable campus.

However, the sustainability agenda took an increasingly important role in NUS’ development plans and the Campus Sustainability Committee, headed by Deputy President of Administration and together with the working committee which is composed of trained staff and professionals from the Office of Estate and Development and the Office of Safety, Health and Environment was later formed in November 2006 to reflect commitment towards sustainable development. The working committee, develop long-term visions and plans for achieving sustainability in key areas whereas the Deputy President of Administration was in charge of advising and supporting the working committee. However, as the long term vision and plans became more developed, the President decided that a dedicated office with full-time staff was required to oversee and push the sustainability agenda to greater heights. Thus, the Office of Environmental Sustainability was set up in October 08.
